ISE's market share statistics continue to be
negatively impacted by trading strategies that are permitted based on a
non-economic rationale. These strategies include dividend trades and
synthetic short interest trades. These trades temporarily inflate and distort
trading volume and market share when transacted.
Monthly Highlights
- ISE was the largest U.S. equity options exchange in May 2009.
- ISE traded more volume than any other options exchange in 1,102 of 2,148
issues in its listings.
